The surgical drain system includes a tube for insertion into the patient through which the fluid drains. The tube extends into the patient and is connected to an adapter having first and second valves for controlling movement of the fluid through the adapter. An attachment includes an insert for opening the first and second valves when inserted into the adapter allowing the fluid to drain into the attachment when the insert is fully seated. A retraction mechanism may be incorporated preventing more than one use of the insert. ## Claims ### Claim at position 1 1-58. (canceled) ### Claim 59 A surgical drain system for draining fluid from a patient, comprising: an adapter for insertion into the patient through which the fluid drains, said adapter having first and second valves for controlling movement of the fluid through said adapter; and an attachment including a male insert for opening said first and second valves when inserted into said adapter and allowing the fluid to drain into said attachment when said male insert is fully seated; wherein a portion of said male insert is bulbous and a portion of said adapter is a bulbous cavity positioned between said first and second valves for receiving the bulbous portion of said male insert. ### Claim 60 (depends on 1) The surgical drain system for draining fluid from a patient of claim 1, wherein said bulbous portion of said male insert and said bulbous cavity form an interference fit when said male insert is fully seated. ### Claim 61 (depends on 1) The surgical drain system for draining fluid from a patient of claim 1, further comprising a tube extending from said adapter into the patient. ### Claim 62 (depends on 1) The surgical drain system for draining fluid from a patient of claim 1, wherein said adapter includes a flange positioned externally of the patient. ### Claim 63 (depends on 1) The surgical drain system for draining fluid from a patient of claim 1, wherein said first valve is positioned inside of the patient. ### Claim 64 (depends on 1) The surgical drain system for draining fluid from a patient of claim 1, further comprising an attachment tube extending between said male insert and said attachment. ### Claim 65 A surgical drain system for draining fluid from a patient, comprising: a tube for insertion into the patient through which the fluid drains, said tube extending from an adapter into the patient and having first and second valves for controlling movement of the fluid through said adapter; and an attachment including a male insert for opening said first and second valves when inserted into said adapter, wherein said male insert acts as a stent maintaining said first and second valves in an open position allowing the fluid to drain into said attachment. ### Claim 66 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said male insert includes a stem maintaining said first valve in the open position and a neck maintaining said second valve in the open position. ### Claim 67 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said male insert includes a substantially bulbous portion, and said adapter includes a bulbous cavity positioned between said first and second valves for receiving said substantially bulbous portion. ### Claim 68 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, further comprising an attachment tube extending between said male insert and said attachment. ### Claim 69 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said attachment further includes one of a cap for sealing the port, a syringe, a vacuum source, a bulb reservoir, a reservoir, a reservoir having osmotic matter positioned therein for absorbing fluid, a fitting connected to a fluid source for injecting the fluid of the fluid source into the patient, and a surgical access fitting. ### Claim 70 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said tube includes a plurality of holes in at least a proximal portion of said tube. ### Claim 71 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said tube is substantially elliptical in shape. ### Claim 72 (depends on 7) The surgical drain system for draining fluid from a patient of claim 7, wherein said tube includes ribs along a lumen of said tube. ### Claim 73 A surgical drain system for draining fluid from a patient, comprising: an adapter for insertion into the patient through which the fluid drains, said adapter having first and second valves for controlling movement of the fluid through said adapter, and an attachment including a male insert positioned within said adapter for opening said first and second valves and allowing the fluid to drain into said attachment, said male insert including a valve which precludes fluid flow when said male insert is withdrawn from said adapter. ### Claim 74 (depends on 15) The surgical drain system for draining fluid from a patient of claim 15, wherein said adapter includes a tube having a proximal end within the patient and a distal end adjacent said adapter. ### Claim 75 (depends on 16) The surgical drain system for draining fluid from a patient of claim 16, wherein said tube includes a plurality of holes in at least a proximal portion of said tube. ### Claim 76 A surgical drain system for draining fluid from a patient, comprising: a tube for insertion into the patient through which the fluid drains, said tube connected to an adapter having first and second valves for controlling movement of the fluid; an insert for opening said first and second valves when inserted into said adapter and allowing the fluid to drain when said insert is fully seated; and a retraction mechanism for preventing more than one use of said insert. ### Claim 77 (depends on 18) The surgical drain system for draining fluid from a patient of claim 18, further comprising an attachment for collecting the fluid drained from the patient. ### Claim 78 (depends on 18) The surgical drain system for draining fluid from a patient of claim 18, wherein said retraction mechanism includes said insert, a connector, a spring, and a lock ring. ### Claim 79 (depends on 18) The surgical drain system for draining fluid from a patient of claim 18, further comprising a housing supporting said retraction mechanism.
